DFB Semiconductor Laser With Discrete Coupling Coefficient Based on the Equivalent Technique

Four Channel DFB Laser Array Based on the Reconstruction-Equivalent-Chirp Technique for CWDM Systems

We report the first experimental realization of four-channel DFB laser array with equivalent phase shift (EPS) based on the reconstruction-equivalent-chirp (REC) technique for CWDM systems. OCIS codes: (140.0140) Lasers and laser optics; (140.5960) Semiconductor lasers

Mutual injection locking of a fibre laser and a DFB semiconductor laser - Electronics Letters

ing that this power level causes little SHB. When the current is increased to 70mA (‘17ns’), the SHB increases. After the mode change (‘3011s’) the carrier density is highly asymmetric, with a large build-up of carriers at the rear facet. Further simulations showed that the time between the second transient and the onset of the mode change decreases when the drive current is increased, possibly...

Transfer-Matrix Analysis of Optical Bistability in DFB Semiconductor Laser Amplifiers with Nonuniform Gratings

We present a transfer-matrix method capable of simulating the effects of nonuniform gratings on the filtering, amplification, and bistability characteristics of distributed feedback (DFB) semiconductor laser amplifiers. The linewidth enhancement factor is incorporated in a way that allows direct gaintuning of the bistability hysteresis. As an example, we compare a /4 phase-shifted DFB amplifier...

Dynamics of a semiconductor laser array with delayed global coupling.

We study the dynamics of an array of single mode semiconductor lasers globally but weakly coupled by a common external feedback mirror and by nearest neighbor interactions. We seek to determine the conditions under which all lasers of the array are in phase, whether in a steady, periodic, quasiperiodic, or chaotic regime, in order to maximize the output far field intensity. We show that the del...
